System Power; Maximum Storage - HP 201723-B21 - StorageWorks Modular SAN Array 1000 Hard Drive Reference Manual

Introduction

System Power

Power to the MSA1000 does not shut off completely with the power switch. The
two positions of the front panel power switch should be considered as on and
standby, instead of on and off. The standby position removes power from most of
the electronics and the drives, but portions of the power supply and some internal
circuitry remain active.
Consequently, to remove all power from the MSA1000 storage system, you must
disconnect the power cord from the storage system. In environments with multiple
power supplies, you must disconnect all power cords to remove power completely
from the MSA1000 storage system.

Maximum Storage

A maximum of 14 1-inch Universal drives can be installed in the MSA1000. Up to
two additional external storage enclosures can be cascaded from the MSA1000,
expanding the capacity to 42 drives. Refer to the MSA1000 website:
www.hp.com/go/msa1000, for the most up-to-date information on supported
drives and enclosures.
